The IUPAC numerical multiplier is a system of prefixes used in chemistry to indicate the number of atoms or groups in a molecule.
Cr(η 6-C 6 H 6) 2, named as bis(η 6-benzene)chromium as all of the (contiguous) atoms in the benzene ligands are involved their position does not have to be specified [(1,2,5,6-η)-cycloocta-1,3,5,7-tetraene](η 5-cyclopentadienyl)cobalt in this only two (at positions 1 and 5) of the four double bonds are linked to the central atom.
Tris(dimethylamino)gallium dimer, formally bis(μ-dimethylamino)tetrakis(dimethylamino)digallium, is an amide complex of gallium. This compound may be used as a precursor to other gallium complexes. Commercially available, this compound may be prepared from lithium dimethylamide and gallium trichloride. [1]
Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups. It is sometimes referred to as Kobayashi's anion in honour of Hiroshi Kobayashi who led the team that first synthesised it. [1]
The pentakis icosidodecahedron is a common geometry for geodesic domes derived from the icosahedron. Buckminster Fuller referred to it as the 2-frequency alternate geodesic subdivision of the icosahedron, because the edges are divided into 2 equal parts and then lengthed slightly to keep the new vertices on a geodesic great circle, creating a polyhedron with two distinct edge lengths and face ...
Tetrakis(triphenylphosphine)platinum(0) is the chemical compound with the formula Pt(P(C 6 H 5) 3) 4, often abbreviated Pt(PPh 3) 4. The bright yellow compound is used as a precursor to other platinum complexes.
At the time of her death, O’Connor’s estate was worth £1.7 million but reduced to £ 1.4 million ($ 1.75 million) after debts, legal fees, and funeral costs.
The tetrakis hexahedron is the Kleetope of the cube, formed by adding a square pyramid to each of its faces; The pentakis dodecahedron is the Kleetope of the dodecahedron, formed by adding a pentagonal pyramid to each face of the dodecahedron. [4] The base polyhedron of a Kleetope does not need to be a Platonic solid.
